Phison Demonstrates Gen5 SSD Controller on AMD X670 Platform Reaching 12.5GB/s Read and 10GB/s Write

The Phison PCIe Gen5 SSD controller is fast

Phison Electronics demonstrated the capability of its next-generation PCI Express 5.0 storage solution.

The Phison E26 SSD platform engineering sample was attached to AMD and Intel PCIe Gen5 compatible systems. It can be clearly seen that the ASUS X670 Crosshair Hero motherboard was used for a quick demonstration.

Earlier this week, Phison unveiled its PS2026-E26 platform which targets PCIe 5.0 x4 storage solution for consumer and enterprise solutions. This interface alone is capable of delivering 15.8 GB/s in each direction, theoretically doubling the bandwidth compared to Gen4.

In a quick video demonstration, the company showcased its Gen5 SSD E26 storage hitting over 12,457MB/s and 10,023MB/s reading and writing in the CrystalDiskMark SEQ1M (Q16T1) test. This test device uses the latest 3D TCL NAND Flash memory from Micron.

It goes without saying that this demo does not show the final product, but rather a platform of potential solutions based on the Phison controller. So far, we have only seen one company announce its upcoming products based on the Gen5 interface. Apacer/Zadak claim their next-gen NVMe 2.0 storage will deliver up to 13,000MB/s read and 12,000MB/s write, the company claims.

Intel has yet to confirm whether its upcoming 13th-gen desktop “Raptor Lake series” will have the same bottleneck as Alder Lake, which is a maximum of 16 Gen5 lanes shared between GPU and storage. AMD has already confirmed that 24 Gen5 lanes will be available for X670-based systems, theoretically allowing one Gen5 GPU to work with two Gen5 SSDs.
